Summary

The goal of this modified pilot RCT is to evaluate the effects of the intervention (online platform) on tobacco-related knowledge, attitudes and intentions on smoking among local primary 5-6 school students. The main questions it aims to answer are: * Is the intervention effective in improving tobacco-related knowledge (including alternative smoking products (ASPs) and tobacco control development in the world and Hong Kong)? * Is the intervention effective in improving tobacco-related attitudes and intentions (including ASPs and tobacco control development in the world and Hong Kong)? Researchers will compare the questionnaire results from students to see if intervention groups (students doing tobacco-related questions on the online quiz platform) will have better tobacco-related knowledge, higher anti-tobacco attitudes and lower intention to smoke.
